<P>PROBLEM TO BE SOLVED: To provide a solid oxide fuel cell system capable of realizing simplicity of the structure. <P>SOLUTION: The solid oxide fuel cell system is provided with a control means for controlling operation of the solid oxide fuel cell 6 and an air-blowing device 8, a condensation recovery means 50 for condensing and recovering steam included in a combustion exhaust gas, and a condensed water supply means 52 for supplying condensed water condensed and recovered to a reformer 4. When the operation temperature of the solid oxide fuel cell 6 exceeds an established upper limit temperature, the control means determines whether or not the quantity of condensed water condensation recovered is larger than the quantity of condensed water necessary for reforming of the raw fuel material at the reformer 4 based on the environmental parameter in the surrounding of the solid oxide fuel cell 6, and when it determines that it is more than the quantity of the condensation water necessary for reforming of the raw fuel material, it increases the blowing quantity of the air-blowing device 8, and when it determines that it is less than the quantity of condensed water necessary for reforming of the raw fuel material, it reduces the power generation output of the solid oxide fuel cell 6. <P>COPYRIGHT: (C)2010,JPO&INPIT |
